Who is Beta - Kramer

• Beta-Kramer is a Ruud Lighting Company• Incorporated in 1982• Largest Privately Held Lighting Manufacturer in

the world• Complete line of LED outdoor (and indoor)

fixtures that set the industry benchmark for energy efficiency

Beta LED “Total Systems

Approach”

Key To Specifications & Evaluation

• Delivered Lumens• How To Compare to HID• How to compare to other LED

products

LED Overview

#title#

Lumen output – HID and LED

LED Overview

#title#

Why Use LED Luminaires?

• Increased Uniformity in Illuminating the Roadway– Lower Average Lighting Levels

– Maintenance of Minimum Lighting Levels

• Exceptionally Long Lives – 100,000 hours +– Much Lower Maintenance Costs

• Substantial Energy Savings– Not Uncommon to Achieve 50% savings from Current HID Lighting

Systems

• High Color Temperature White Light

– Studies Indicate Increased Visual Acuity

#title#

Products Available

• The Edge by BetaLED– Area Rectangular

– Area Round – Direct & Spider Mount

– Pedestrian Scale Pathway Bollard

– Security / Wall Pack

– Canopy

– Parking Structure

• LEDway Street Smart – Roadway Lighting

#title#

“Life”

• LED manufacturers are NOT consistent with life ratings

• IESNA 30% Lumen Depreciation

• Do you define “Life” by the robustness of the Driver?

LED Overview

#title#

Start with the Right LED

• High Brightness, Super-White

– 1 Watt per LED

• High Quality Supplier – Cree, etc.

• Output “watts” will range from 20 – 240 Watts (1-12 light bar modules)

Total Systems Approach

#title#

Light Bar

• 10 or 20 LEDs per light bar

• Modular Design

• Designed to grow as LED technology evolves


#title#

Junction Temperature

What is Junction Temperature Tj ?

How is it measured?

The Beta LED Junction Temp Curve

LED Overview

#title#

Heat Sink

• Proper thermal management is key to low junction temps

• Thermal management = longer life

• Be wary of LEDs in traditional fixture designs


#title#

Heat Sink


• Proper Management of Junction Temperature

#title#

EDGE Product Housing

• Open Mesh Design and Optimized Heat Management


#title#

Junction Temperature Conclusions

• Be wary of LED’s in “traditional” fixture designs.

• The higher the junction temperature the lower the initial light output

• The higher the junction temperature, the faster the lumen depreciation (shorter “life”)

• Look for a fixture that is designed with sufficient heat sinking

LED Overview

#title#

Thermal Management

• Less Heat = More Light– Maximize Initial Light Output

• Less Heat = More Life– Minimize Light Loss Over Time
